PROBLEM TO BE SOLVED: To provide a method for synthesizing an asymmetric allylamine from an imine in high yield and in high asymmetry yield.
SOLUTION: The method for synthesizing an asymmetric allylamine represented by formula (6) (wherein R1is selected from the group consisting of o-, m- and p-substituted aromatics, naphthyl, an alkenyl, an alkyl, furyl, thiophenyl and a pyridine group; and R2is selected from the group consisting of benzyl, an aromatic ring substituted benzyl, allyl, and methyl) comprises reacting an imine represented by formula (5) with an allyltributylstannane in the presence of a bis-π-allylpalladium complex represented by chemical formula (2a) as a catalyst.
